Winna
TRUST SCORE
7.5/10
Above average
Arbitrage betting not allowed
Winna's Sports Terms explicitly prohibit arbitrage betting: “The use of arbitrage strategy, which involves exploiting differences in Odds across different bookmakers/sportsbooks to guarantee profit, is strictly prohibited on the Sportsbook.” Bets found to be arbitrage face “immediate cancellation of the Bets and permanent restrictions.”
Supports 13 cryptocurrencies
Sportsbook powered by BetBy
Overview
Winna is a crypto casino and sportsbook that launched in summer 2024, led by co-founder/CEO Paul Martens, and closed a $15M seed funding round in December 2024. It's operated by GG Gaming (Costa Rica-registered). At the time of its funding announcement the CEO said an Anjouan (Comoros) licence was "expected in January"; Winna's site currently states it is licensed by the Tobique Gaming Commission (New Brunswick, Canada) instead — this apparent change in licensing jurisdiction isn't confirmed by a single authoritative source and is worth treating as an open question.

Bonuses, withdrawals & KYC
Instant Rakeback accrues per wager, claimable every 7 min
Third-party source cites steep 250x wagering req (unconfirmed)
Markets itself as no-KYC for standard play
Withdrawals typically process within minutes (~$20 min)
Detailed background research on stated policy — broader than any single number in the score breakdown above, though it informs it. Where an operator's own terms couldn't be fetched, that's noted and the figures are flagged as third-party rather than operator-confirmed.
Bonus policy
"Instant Rakeback" accrues a percentage of wagers, claimable every 7 minutes (exact percentage not disclosed officially); a VIP-only "Lossback" returns up to 25% of net losses for Platinum-tier+ players. A third-party review cites a 250x wagering requirement on the welcome bonus with a Platinum-status deadline — unconfirmed against Winna's own (inaccessible) bonus policy page.
Withdrawal timeframe
Crypto-only. Winna's own terms pages didn't return readable content for verification; third-party reviews describe withdrawals as typically processed within minutes, with a roughly $20 minimum.
KYC / verificationKYC conditional
"Conditional" means no KYC is required just to sign up and play. Verification is only requested in some cases — most commonly when withdrawing, or if suspicious activity is flagged.
Marketed (including by the operator, per third-party quoting) as a "no-KYC" casino for standard play, though terms reportedly allow verification requests at any time. A third-party source cites an approximate €2,000 threshold for enhanced verification — unconfirmed against Winna's own AML/KYC page, which didn't return readable content.
